Figure 1. MPC5744P expansion board and main board system

3.1 Methods of operation

Power to the expansion board is supplied via three options:

1. The MPC5746MMB main board generates the 5 V/3.3 V/1.25 V supplies to the expansion board

via the interface connectors.

2. In standalone configuration, external 5 V/3.3 V/1.25 V supplies are provided to the expansion

board via the terminal block.

3. In standalone configuration, a single 12 V supply is input to the expansion board via the 2.1 mm

power connector. The PwrSBC generates the 5 V/3.3 V high-voltage power. The NPN transistor

drives the core supply using internal regulation.

4 EVB configuration

This section provides information on how to configure the jumper settings on the EVB. Default settings

are marked as such. Figure 5 provides a top view of the EVB and shows the location of each jumper.

4.1 Power source

The default jumper settings are configured for using the EVB with the MPC5746MMB main board as

shown in Figure 2. Power is supplied from the main board to the EVB via the two interface connectors.

1. Not all expansion boards include the PwrSBC device. Check whether the PwrSBC (U3) is installed on the expansion board to

determine whether standalone operation using a single 12 V supply can be used. Refer to Figure 5 for the location of U3.

4.3 Boot configuration

Table 7 shows the J7 switch settings to configure the boot configuration. When booting from UART or

CAN, connect the expansion board to the main board and use the interface connectors described below.

4.4 Clocks

The EVB provides the following options for clock sources:

4.7.4 PwrSBC IO_0:5

Table 16 shows the J10 jumper which allows access to the PwrSBC IO_x pins. The IO_x pins are inputs

to the PwrSBC for monitoring various signals.

J10 also provides connection between the FCCU_F[0:1] and PwrSBC IO_2:3 pins to allow the PwrSBC

to monitor the status of the MCU’s FCCU error output pins.

5 Reset switches

The push-button switches (SW1 and SW2) provide external power-on-reset and reset to the MCU.

Table 17 shows the reset switches.

6 Connectors

Table 18 lists the connectors available on the EVB.

8 Test points

Test points shown in Table 24 are available to allow probing of various voltages.

9 Port pin to main board mapping

When the expansion board is connected to the main board, the port pins are routed to the main board via

the interface connectors. Table 25 shows the port pin mapping to the main board connectors.

For example, port pin PB4 can be accessed on the main board from connector P9 pin 8.
